When I wanted to give a smart watch to my friend, I was advised to choose a fitbit from https://findthedecision.com/best-fitbit-for-men/ where I found a detailed description of 10 Best Fitbit For Men in 2019 and could not make a mistake when choosing this gadget
When I was choosing a watch for myself, I realized one thing that you need to choose the watch that you can afford to buy, because their functions are almost the same. Both Samsung and Garmin watches are dustproof and water-resistant up to 50 meters, they have a branded glass that is resistant to damage, and can sync with your mobile phones wirelessly. Both are compatible with Android and iOS, but only the Galaxy watch is equipped with a Wi-Fi connection, see https://ohmywearables.com/ for more details. The choice is yours.
